Qualifications and voting[edit]

From 1947 through 1956, each BBWAA voter used discretion as to who qualified as a rookie. In 1957, the term was first defined as someone with fewer than 75 at bats or 45 innings pitched in any previous Major League season.[1] This guideline was later amended to 90 at bats, 45 innings pitched, or 45 days on a Major League roster before September 1 of the previous year.[1] The current standard of 130 at bats, 50 innings pitched or 45 days on the active roster of a Major League club (excluding time in military service or on the disabled list) before September 1 was adopted in 1971.[1][5]

Since 1980, each voter names three rookies: a first-place choice is given five points, a second-place choice three points, and a third-place choice one point. The award goes to the player who receives the most overall points.[1][6]Edinson Volquez received three second-place votes in 2008 balloting despite no longer being a rookie under the award's definition.[7][8]

The award has drawn criticism in recent years because several players with experience in Nippon Professional Baseball (NPB) have won the award, such as Hideo Nomo in 1995, Kazuhiro Sasaki in 2000, and Ichiro Suzuki in 2001. The current definition of rookie status for the award is based only on Major League experience, but some feel that past NPB players are not true rookies because of their past professional experience. Others, however, believe it should make no difference since the first recipient and the award's namesake played for the Negro Leagues prior to his MLB career and thus could also not be considered a "true rookie".[9][10] This issue arose in 2003 when Hideki Matsui narrowly lost the AL award to Ángel Berroa. Jim Souhan of the Minneapolis Star Tribune said he did not see Matsui as a rookie in 2003 because "it would be an insult to the Japanese league to pretend that experience didn't count."[9]The Japan Times ran a story in 2007 on the labeling of Daisuke Matsuzaka, Kei Igawa, and Hideki Okajima as rookies, saying "[t]hese guys aren't rookies."[10] Past winners such as Jackie Robinson, Don Newcombe, and Sam Jethroe had professional experience in the Negro Leagues.
